A novel C20-diterpenoid alkaloid with an unprecedented 19 carbon atoms, designated as tatsienensine (1), was isolated from the whole plant of Delphinium tatsienense. The structure of the compound and its relative configuration were established by NMR techniques and single-crystal X-ray diffraction.
